Well, I still have my first computer, an Apple II+, an Apple IIe, an Atari 800XL, and Atari 130XE, the A1000, the A500, an old 486DX-66, and my current main machine, a PIII-500 that I built myself. I finally discarded an older non-functional PC XT, along with a few 386 boxes that were given to me.

The biggest problem I have is not having enough room to set them all up. I've managed to make room to hook up the A500 and the Apple IIe along with my PIII, but that's all the space I can spare.
